Do I need a company to do a one-off insert for a MUD base?
Do I need a company to do a one-off insert for a MUD base?
(OP)
Hello, not an engineer but learning enough to be dangerous. We have a small plastic part (.75 x .25 x .33" in PC resin) that ties an assembly together. It has a very simple rectangular shape with a single hole in the center. Could we avoid the high cost of an injection mold tooling company ($4800 - 5800 quotes) and have a competent machine shop CNC the aluminum insert mold plates for use in a small MUD base? The bases are relatively inexpensive and we can use them for other small parts we'll need in the future. There are a lot of injection molding companies here in SoCal that could then run the parts for just the setup and cycle time cost. Am I way off base or is this entirely feasible?
Thanks
Thanks

Don't forget you'll have to put in the ejection system as well as machine the cavities.
You could try and find a moulder with a MUD base already?
One possibility might be to use a standard steel bolster and put changeable cavity inserts in it - either alloy or steel. We have several in hand for small volume jobs.

I've bought a lot of scrap from those things, and very little acceptable product.
If your PC part really is as simple as you describe, consider having it CNC milled from sheet directly, with no mold involved.
